摘要:氟化物在化学,工业和生命科学中很重要.在一种新方法中,应用对氢诱导极化(phip)增强(全氟正己基)乙烯和(全氟正己基)乙烷的19 F Mr信号.出乎意料的是,尽管与添加的质子的耦合可以忽略不计,但末端cf 3基团却显示出最高的极化强度.为了澄清这种非直觉的极化分布,比较了氘代氯仿和丙酮中的信号增强,并获得了19 F-19 F Noesy光谱以及19 F T 1值通过NMR光谱法测量.通过使用cf 3基团的非常好分离和增强的信号,记录了超极化线性半氟化烯烃的前19 F Mr图像.

摘要:New organosilicon compounds of the formula R represents a hydrogen radical with 1 to 6 carbon atoms, or a phenyl radical; R1, R2, R3 and R4 are the same or different and represent hydrogen or methyl radicals; R5, R6, R7 and R8 are the same or different and represent hydrogen, fluorine or hydrocarbon radicals with 1 to 8 carbon atoms, or fluorinated hydrocarbon radicals, in which at least one R5, R6 R7 or R8 radicals must be a fluorine or a fluorinated hydrocarbon radical; Y is a hydrolyzable radical, hydroxyl radical or organosiloxanyl radical; A represents in which R9 may be the same or different and represents a hydrogen or a methyl radical; and a has a value of 0, 1, 2, or 3. These compounds can be synthesized by reacting a 2-norbornene derivative of the general formula with an organosilicon compound having the formula in the presence of a catalyst, known as such for the addition reaction of -SiH to olefinic double bonds, if necessary at an elevated temperature and/or an elevated pressure. They are used to modify the surface of solids, especially of finely divided silica.

摘要:Stoichiometric and catalytic chemical transformations may be carried out in solution using novel fluorous multiphase systems (FMS). The term 'fluorous' is defined as a carbon-fluorine bond rich organic molecule. The FMS consists of a fluorous phase containing a fluorous solvent, typically a fluorocarbon or a fluorohydrocarbon and a reagent or a catalyst containing a sufficient number of fluorous moieties to render it preferentially soluble in the fluorous solvent without impairing the ability of the catalyst or reagent to be effective in the reaction and while maintaining the reaction in a liquid or fluid phase. The nonfluorous solvent may be any suitable organic or nonorganic solvent(s) with limited or no solubility in the fluorous solvent that is effective for dissolving the reactant(s) and most desirably, for separating the resulting product(s). Typically, such solvents have a Hildebrand solubility parameter of at least about 18.0 MPa1/2. Appropriate fluorous moieties are linear, branched and carbocyclic fluorocarbon alkyl chains with high carbon numbers. FMS reagents and catalysts can be prepared by (1) fluorination (i.e., replacement of C--H bonds with fluorine); (2) fluorofunctionalization, e.g., the attachment of fluorous moieties to the reagents or catalysts; or (3) by total synthesis. The invention is useful in separations technology and in catalyst design and synthesis.
